GTN-Pro 6.4 Tablet CR
Prescription Required
Product introduction
GTN-Pro 6.4 Tablet CR is used to treat and prevent heart-related chest pain (angina). Angina occurs when the heart muscle is not getting enough blood. This medicine works by relaxing and widening blood vessels so blood can flow more easily to the heart.
GTN-Pro 6.4 Tablet CR should be taken in the dose and duration as advised by your doctor. It may be taken with or without food, preferably at a fixed time each day. Do not consume more than the recommended dose, as this may have harmful effects on your body. You can develop tolerance to this medicine over time, which means that the same dose becomes less effective. You have to stick to a really specific dosing schedule to prevent this from happening.
The most common side effect of this medicine is a headache which may be severe. This can sometimes be helped by drinking plenty of fluids and avoiding alcohol. You may also experience lightheadedness, which could increase your risk of having a fall. There are other, rarer side effects, some of them serious. Ask your doctor and read the leaflet which comes with the medicine to make sure you are keeping safe.
Do not use this medicine if you are taking medicines to treat high blood pressure in your lungs (pulmonary hypertension), erectile dysfunction or if you have anemia or glaucoma (increased pressure inside the eye). Always tell your doctor what other health conditions you have and what other medicines you are taking. It is best not to drink alcohol with this medicine as it increases some of the side effects. If you are affected by dizziness, avoid driving. If you are pregnant, planning to become pregnant, or breastfeeding, ask your doctor before taking this medicine.

FAQs
Can I take sildenafil if I am taking GTN-Pro 6.4 Tablet CR?
No, you should not take sildenafil if you are taking GTN-Pro 6.4 Tablet CR. Taking these two medicines together can cause an excessive fall in blood pressure, which may even be life-threatening.
What effect does GTN-Pro 6.4 Tablet CR have on blood pressure?
GTN-Pro 6.4 Tablet CR decreases the blood pressure by relaxing the blood vessels, but is not recommended for the treatment of high blood pressure. The drop in blood pressure may cause lightheadedness, especially when changing your position suddenly.
Does the effect of GTN-Pro 6.4 Tablet CR wear off after some time?
Yes, excessive use of GTN-Pro 6.4 Tablet CR may cause tolerance which means that GTN-Pro 6.4 Tablet CR may lose its effectiveness on you.

What does too much GTN-Pro 6.4 Tablet CR do?
Excess GTN-Pro 6.4 Tablet CR may result in low blood pressure, sweating, nausea, vomiting, headache, weak and fast pulse. It may also cause weakness, lightheadedness on standing and the patient might even faint. The patient will require emergency medical treatment in such a case.
Can I stop using GTN-Pro 6.4 Tablet CR as I feel better now?
Stopping GTN-Pro 6.4 Tablet CR suddenly may bring on attacks of angina, especially if you have been using it for several weeks or more. Talk to your doctor who will advise you to reduce the dose gradually over 4 to 6 weeks before you stop using it completely.
Does GTN-Pro 6.4 Tablet CR stop heart attacks?
GTN-Pro 6.4 Tablet CR is prescribed to prevent attacks of heart-related chest pain (angina) in patients with coronary artery disease. In this disease the blood vessels (coronary arteries) which supply blood to the heart become narrowed because of which the heart has to work harder to get enough oxygen. GTN-Pro 6.4 Tablet CR prevents angina by relaxing the blood vessels so that the heart does not have to work very hard. Also, relaxation of coronary arteries increases the oxygen supply to the heart.
